Description
上述の生理用ナプキンの着色層は、着色剤を有するホットメルト樹脂によって構成されている。例えば、着色層の色を濃くするためには、着色剤を有するホットメルト樹脂の量を多くすることが考えられる。しかし、ホットメルト樹脂の量が多くなり過ぎると、体液の透過性が低下するおそれがある。
一方、ホットメルト樹脂の量を少なくすると、表面シートと吸収体との間の接着性が低下するおそれがある。
図1から図4を参照して、本発明の第1の実施形態に係る吸収性物品1について説明する。図1は、吸収性物品の平面図である。図2は、図1に示す吸収性物品の背面図である。図3は、図1に示すA−A断面図である。図4は、図3に示すB部分を模式的に示す拡大断面図である。本実施形態に係る吸収性物品1は、例えば、生理用ナプキンである。
したがって、吸収性能を保持しつつ、装飾性を高めることができる。
次いで、図5及び図6に基づいて第2の実施形態に係る吸収性物品1Aについて説明する。なお、以下の実施形態において、第1の実施形態と同様の構成については、同符号を用いて説明を省略する。
次いで、図7に基づいて第3の実施形態に係る吸収性物品1Bについて説明する。第3の実施形態に係る吸収性物品1Bの吸収層32は、着色層31と異なる色の着色剤を有している。よって、着色層31と吸収層32とが異なる色で着色されている。なお、第3の実施形態の着色層31及び吸収層32の形状は、第1の実施形態の着色層31及び吸収層32の形状と同様である。
次いで、図8及び図9に基づいて第4の実施形態に係る吸収性物品1Cについて説明する。第4の実施形態に係る吸収性物品1Cは、吸収体30と表面シート10との間に中間シート35が配置され、中間シート35には、着色層31と異なる色で着色された表示部35aが設けられている。表示部35aは、平面視にてハート型の絵柄を示すように構成されている。着用者は、表面シート10を介して表示部35aを視認できるように構成されている。
次いで、図10に基づいて第5の実施形態に係る吸収性物品1Dについて説明する。第5の実施形態に係る吸収性物品1Dは、着色層31が吸収層32よりも長手方向及び幅方向において長く構成されている。このように構成された吸収性物品によれば、中間シート35に形成された絵柄と圧搾部80とによる装飾を施すことができ、かつ吸収層32の輪郭を目立たせることができる。
